^{†}The graphical symbols of the `e'glide planes are applied to the diagrams of seven orthorhombic A, C and Fcentred space groups, five tetragonal Icentred space groups, and five cubic F and Icentred space groups.
^{‡}Glide planes d occur only in orthorhombic F space groups, in tetragonal I space groups, and in cubic I and F space groups. They always occur in pairs with alternating glide vectors, for instance and . The second power of a glide reflection d is a centring vector.
